EXCLUSIVE: Doctor Odyssey's maiden voyage appears to be going smoothly.

Ryan Murphy’s latest procedural series premiered last week on ABC, and so far the premiere episode has drawn 13.6 million cross-platform viewers in its first week, Disney says. That’s an impressive 230% increase from the episode’s live + same-day audience of 4.13 million.

This is a monster start for Doctor Odyssey. While most shows grow their audience significantly in the week after they air, it’s pretty rare for an episode, once available on streaming, to average 10 million viewers in that time frame — let alone blow past that mark.

Within three days of viewing, the cruise ship drama had 7.59 million viewers, making it ABC’s best drama premiere in four years, according to Disney. And after its first full day on Hulu, it was No. 1 on the streamer’s Top 15 Today list, where it’s remained ever since.
